That's what I assumed as well, since Gilt doesn't make any sense with how names in 40k are usually composed. Editor error maybe?

Nick, hi! A random question: as a non-native English speaker, I tend to mentally translate English text into my native language to better understand the meaning. Alas, I'm absolutely dumbfounded by Stygian Gilt. Does it mean a layer of gold? Or is it a piggie lol? Or is it just a name?

але ж ЯК ВІН ВОЛАВ, пропустити дзвінок чи будильник було неможливо

Нікого на ім'я Калас поблизу нема?
